How to avoid notification service dead lock?

I have two adapter notification service,

1st adapter notification service: whenever record is inserted into table A, then record will be inserted into B table.

2nd adapter notification service: whenever record is inserted into table B, then record will be inserted into A table.

This scenario will lead into the deadlock, how to avoid this?

Thanks
